Extremely happy with the quality, fitment, and sound of this exhaust. Everything also bolted up with very minor fitment tweaking, which is a testament to the engineering behind this exhaust. My only complaint is that Stillen's instructions calls for you to reuse your exhaust gaskets and bolts... something which is not really feasible for a 12 year old car in my case. Luckily there were stores nearby that had the hardware on hand so it was only a minor inconvenience.

Extremely happy with this exhaust. It has great tone, & volume. Only other Intake / Exhaust mod is an NWP 75mm big bore throttle body.

The best exhaust for 03-06 g35 sedans. Fitment is perfect and the sound is the best sound. Can be silent if you want and loud high pitched vq scream around 4,500 rpm. Looks amazing on the car. The staggered tips follow the subtle curve of the rear bumper. The design is magnificent. Ive had mine for 8 years now and still looks amazing and sounds amazing - no leaks
